A Mount Sinai study, published in the journal Nature Neuroscience, provides important insight into how microglia, cells that form a branch of the immune system inside the brain, go about their job of clearing out dying and non-functional neurons – and... Continue Reading →
Long-term use of either cannabis or cannabis-based drugs impairs memory say researchers. The study has implications for both recreational users and people who use the drug to combat epilepsy, multiple sclerosis and chronic pain. They found that mice exposed to the drug... Continue Reading →
What are those red filaments in the sky? It is a rarely seen form of lightning confirmed only about 30 years ago: red sprites. Recent research has shown that following a powerful positive cloud-to-ground lightning strike, red sprites may start as 100-meter balls of ionized air that... Continue Reading →
The SDO spacecraft is in another eclipse season as of Feb. 6, 2019. This begins a several week period when the Earth briefly blocks SDO’s view of the Sun each day. In fact, because SDO orbits above the Mountain Time... Continue Reading →
A growing collection of anecdotal stories raises the possibility that nerve injury in an arm or a leg can act as a trigger for the development amyotrophic lateral sclerosis, or ALS -- a progressive neurodegenerative disease also known as Lou... Continue Reading →
Bubbles don’t stick around in pure water. Surfactants are needed to stabilize the thin liquid film for longer than the blink of an eye. But that’s not necessarily the case for other liquids. As the video below shows, a bubble in isopropyl... Continue Reading →
Scientists have discovered a “Big Bang” of Alzheimer’s disease – the precise point at which a healthy protein becomes toxic but has not yet formed deadly tangles in the brain. A study from UT Southwestern’s O’Donnell Brain Institute provides novel... Continue Reading →
Eta Carinae may be about to explode. But no one knows when - it may be next year, it may be one million years from now. Eta Carinae's mass - about 100 times greater than our Sun - makes it an excellent candidate... Continue Reading →
The geologic time scale (GTS) is a system of chronological dating that relates geological strata (stratigraphy) to time. It is used by geologists, paleontologists, and other Earth scientists to describe the timing and relationships of events that have occurred during Earth's history.
